During building Renci.SshNet.Tests-Project Windows Defender pops up and warns me about:
"Malware detected: -Ramson:MSIL/Hasdcrypt.A".
In Visual Studio 2017 I get an error telling me that an error occured during signing and the process was canceled cause the file may contain a Virus or unwanted software.
I suspect it's an false-positive.
Current workaround is to disable Real-Time-Protection if I want to build the Project.
